I went with high expectations and got disappointed

Rating: 5/10 (12 July 2013)

Long story short : The movie is only a pure fight between giants robots and giant monsters. I saw that there are many fans and child's watching this movie and sorry if I will be more critic as I am not a child.
I see this like an Japanese anime implemented as a movie and that's it. Robots fights with giant monsters anime stories were mainly written for 5- 13 year old child's and they were pretty successful .
I guess the target public for this movie is the same, as beside the actual fights the story line is flat , disappointing, with a lot of clichés and seems to be written for this age interval. Why ?
You invest so much in special effects (fights are really good – the only thing I could enjoy) but so less in story scripts , and actors?
Why bother to do amazing special effects (robots/monsters designs and fights) and rap them around with such stupid story? Aliens coming to colonize our planet through a portal. OK good ! They send clone giant monsters to destroy dominant habitant, and you defend with giant robots . Good so far, but why in the world is needed for the robots to be driven by 2 pilots – no sense at all?
How in the world you can really convince the entire world to build a wall as it is better than some super giant robots – is the world really retard in this movie ?
Why after so many years of fighting you have only 2 so called scientist studying the monsters and not an army of them (why in 2013 you need them fighting between them in theories – cliché )
How in the hell you can get pregnant a giant cloned monster? (Why you use "the cocky guy staying with the back to the baby monster after throwing a knife and getting eaten after" cliché? )
How did the pilots returned through portal without having monster DNA ?
How can you get a super strong monster with real natural armor to get cut in half with sword .Yes the effect is amazing but put some physics in the equation , do some minor experiments (through a chicken into a knife and see how much speed or force is needed for it to be cut in 2 ). And it was longitudinal please
How can you really get exploded a super extra mega atomic bomb without having the damaged robot even move  and in this way there are many inconsistencies which I really did not appreciated for a 2013 mega production.
Effect of the fights are really great but all other not.
I really advice for the producer to have a real critic person working with him to have a before releasing feedback to improve the movie itself.
I was really served with a sandwich of great and really bad, I was "UUU" great fights and effects , and soon after I was "WTF" , is this real ?
